| Experimental. Gated by ``CMAKE_EXPERIMENTAL_SYCL``. |

| |
| Default device target selection for the AdaptiveCpp SYCL compiler. CMake |
| reads this variable when first enabling SYCL if |
| :variable:`CMAKE_SYCL_DEVICE_TARGETS` is not defined. The selection is used |
| for compiler identification and testing, and as the default for targets |
| whose :prop_tgt:`SYCL_DEVICE_TARGETS` property is unset or empty. Subsequent |
| configurations retain the detected default selection. |
| |
| The value is a semicolon-separated list of compilation flows, each optionally |
| followed by a colon and a comma-separated list of architectures. See |
| :prop_tgt:`SYCL_DEVICE_TARGETS` for examples of AdaptiveCpp target names. |
| |
| For example: |
| |
| .. code-block:: console |
| |
| $ export ACPP_TARGETS='cuda.explicit-multipass:sm_80,sm_86;hip.explicit-multipass:gfx90a' |
| |
| If this environment variable is not defined, CMake also checks |
| :envvar:`HIPSYCL_TARGETS` before using the compiler's installation default. |
